Hi All
Has anyone built a toploader that is the same size and with the side tie outs as the HH backpacker ultralight a-sym?

I'd like the HH but would like to make a toploader so I can just climb in and look out of but still use the std HH tarp. So it would need to end up the same length and I wonder about the folded ends too.

Anyone try this and have some measurements?
Thanks
Gunn
